Wrong transition alt during descent

Recommended Posts

Hi,I consistently set my transition altitude to 10,000 ft in the FMC. During climb the pressure goes yellow with a box around it at 10,000 ft as it should. On descent the STD wants to transition at 18,000 ft. Is there a way to have the same transition altitude apply to both climb and descent?tia--qnh

I'm not at my home PC right now but from memory I *think* you need to change it in both the Climb and Descent pages (1/3 and 3/3) of the VNAV section on the FMC. The theory being that transition alts might be different in your departure and arrival areas.See if that works, if not I'm totally off course myself!

Mark is right, it has to be input on both pages. Anticipating the next question - yes, there is a small error on the DES page, the label should actually read TRANS LVL as in Transition Level, which is what you use during descent. The value itself is correctly expressed as a FL, i.e. if you input 8000 it will show FL080.
